Answer:

3.6 centimeters in 4 seconds.

Step-by-step explanation:

Given, 2.7 centimeters in 3 seconds. x centimeters in 4 seconds.

We will solve this problem by unitary method.

since in 3 seconds = 2.7 centimeters

therefore, in 1 second = $\frac{2.7}{3}$

Therefore, in 4 seconds = $\frac{2.7}{3}$ × 4

= $\frac{10.8}{3}$

= 3.6 centimeters

3.6 centimeters in 4 seconds.

Answer:

Step-by-step explanation:

Two of the four given equations have a y-intercept of (0, -4). Eliminate the remaining two. Next, notice that the shaded area is ON or BELOW the solid line. These characteristics correspond to

y ≤ (1/3)x - 4

Write an equation in the variables x and y for the line that passes through the point (4, 7) and that is perpendicular to the li

Brrunno [24]

First of all, we need to find the slope of the given line, writing it in the $y=mx+q$ form and reading the $m$ coefficient:

$2x + 2y = 14 \iff 2y = -2x + 14 \iff y = -x+7$

So, the slope is $-1$

If a line with slope $m'$ is perpendicular to a line with slope $m$ , the following relationship holds:

$mm' = -1$

So, the slope of our line must satisfy

$m(-1) = -1 \iff m=1$

So, we need the equation of a line with slope 1 and passing through (4,7). Given the slope $m$ and a point $(x_0,y_0)$ of a given line, its equation is given by

$y-y_0 = m(x-x_0)$

So, if you plug your values, you have

$y-7=1\cdot(x-4) \iff y = x+3$
